I have always use house panels on my astrovan. First I had a kycora 120 watt panel (6 amps), then I upgraded to a larger sharp 240 watt mono panel ( I seen up to 15 amps when charging my lithium, about 12 amps with agm this is with panel being flat on roof and my 20 amp ecoworthy mppt). Pictures...
If you open up one of the lithium packs this is what you find, maybe less batteries. They use the same 18650 batteries found in laptops. Most are either 3s 10.8 or 11.1 volt, fully charge to 12.6 volts. This one I built myself with 90 batteries 3s 30p which gives me a total of 65 ah. All 90...
None of them showed what amp hour battery they contain, but the poweroak has a 400wh rating (400/12=33ah) it probably has the bigger lithium battery but it doesnt state what it actually has. With lithium they give confusing estimates with the WEIYI 100 watt, they also state 40,800 mah(150 watt)...
You will never overcharge your agm with solar. On my agm I had the absorb/bulk set to 14.4 volts and the float to 14.3 volts (the highest it would go). The 3 years I had it was connected to a solar panel with those voltages. The agms like to be kept at those voltages. To overcharge an agm, you...
The 75 ah vmax will work fine for your modest needs. All the agm's deep cycle are basically the same, even if they say its recommended for trolling motors, they make good aux battery. I was using a car audio agm for my aux battery for 3 years with no problems.
Just try not to let it get too...
lifepo4 is a 4s 12.8 volt battery which is similar to lead acid voltage. Any charge controller mppt or pwm can charge that. As long as the lifeepo4 battery has a BMS, it will stop accepting charging when it reaches full charge, and it will also shutoff power when it reaches low voltage. The...
Instead of a microwave or gas I use a 12 volt roadpro lunchbucket cooker, its small but will heat up a can of food in 20 minutes, uses a total of 5 amps in those 20 minutes. I just use aluminum foil instead of the special liners they recommend. I also replaced the cigarette adapter with a xt60...
You have to run everything from the battery to get reliable voltage. The load out from the controller will give you unreliable power, voltage will go up and down with the sun. For instance if you got a fan hooked up to the controller you notice the rpm go up/down with clouds etc, on my...
When the battery gets drained to 10.1 it won't last long, even if its a deep cycle. For agm to extend its life you shouldnt go below 12.1 (50 percent) at 11.5 volts your at 10 percent which is the safest you can drain any lead acid.
I owned my agm for about 3 years, rarely took it below 12...
I would check the voltage at your agm, it should be about 14.4 volts or lower when the engine is running. It should be lower since its further from the engine. If its less than 14.4 volts, then something else is causing the overheating because no agm will vent at that voltage unless its bad...
the lithium jump starters use the same lithium flat batteries used in remote control planes, usually a 3s 11.1 volt (12.6 fully charged) 3 to 5 amp hour battery. I saw them take one apart on youtube. It might run a fridge for one hour maybe.
Just like the remote control airplane batteries, they...
better to have it and not need it then to need it and not have it.
I have my start battery,
I have my 94 amp hour lithium house battery,
I still have my old house battery kinetik khc2000 agm (102 ah)
I have a fullriver 28ah agm battery (which can replace the start battery in an emergency)
and...
There are many different RC type chargers that charge all types of batteries including lead acid. Many of them are ac/dc and will give your battery a good charge.
I use a triton charger that I bought for 20 dollars to top off my agm batteries that I rarely use, it does a very good job. I also...
my only advice to the topic of discharging a lead acid beyond 50 percent is not to do it.
I had my kinetik khc2000 which is a high end agm (102 ah) for about 3 years, I always had it connected to solar and rarely took it below 50 percent it would usually be at 12.3 volts in the morning...
this is a good option for those with large systems and the price isnt bad for the amps it can handle. I'm also surprise that there arent more of these lithium solar balance chargers available. This is a true lithium charger very similar to the ones use in the RC world.
In my use of lithiums (3s...
You get about 1 amp for every 20 watts of solar.
I was running my 12 volt fridge edgestar fp430 (set to 40 degrees) nonstop 24/7 off of a 120 watt panel and a 75 ah agm battery. The panel produce about 6 amps in full sunlight. My fridge consume 25 amps in a 24 hour period, which was acceptable...
6.34 amps is good for your 100 watt panel. 6.34 amps x 14.09 volts gets you 89 watts. You never going to get the full 100 watts, you only get that at the factory where they test the panel using special gear and methods.
If you took the 9.44 amps x 14.09 you would get 133 watts, which is more...
the load out on mppt controllers can be unreliable. On mine whenever a cloud blocks the sun as soon as the cloud clears (edge of cloud effect), the mppt goes looking for a new max powerpoint and the voltage shoots up pass 14 volts, this always turns off the load out. (built in overvoltage...
to charge from your cigarette lighter while the car is running you dont even need a charger. Your jerry can is something similar to those 12 volt jump packs, the 12 volt jump packs are charged straight from the cigarette adapter. Just connect one of those double male cigarette adapters from the...
with lithiums, they like to inflate the numbers. The xp-10 might say 18,000 mah but your not going to get that. You only get that if you use it to charge something with the USB ports at 5 volts. At higher volts, you might get 4000 mah.
These jump packs use the same high discharge lithium...
